We're dividing 717366 by 86 
The aim is to understand the frequency of 86 in 717366.

Let's proceed to step 1:
When dividing 7 by 86, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Take the next digit (1) from the dividend and append it to 7, then repeat: 71 / 86

Let's proceed to step 2:
86 can be fit into 71 0 times, resulting in a remainder of 71.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 71 to get 71.
Take the next digit (7) from the dividend and append it to 71, then repeat: 717 / 86

Moving on to step 3:
717 divided by 86 is 8 with a remainder of 29.
The next digit of our result is 8. 
Result so far: 8.0
If we subtract 688 from 717, we get 29.
Fetch the next digit (3) from the dividend, attach it to 29 and continue: 293 / 86

Moving on to step 4:
293 divided by 86 is 3 with a remainder of 35.
Use 3 as the next digit of our solution. 
Result so far: 83.0
If we subtract 258 from 293, we get 35.
Take the next digit (6) from the dividend and append it to 35, then repeat: 356 / 86

Let's proceed to step 5:
86 can be fit into 356 4 times, resulting in a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 834.0
The remainder is 12 after subtracting 344 from 356.
Bring next digit (6) of the dividend behind the 12 and repeat the process: 126 / 86

Step 6:
If we divide 126 by 86, we get 1 and a remainder of 40.
Put 1 as the next digit of the answer. 
Result so far: 8341.0
The remainder is 40 after subtracting 86 from 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 7:
The number 86 fits into 400 4 times, leaving a remainder of 56.
Write down 4 as next digit of the result. 
Result so far: 8341.4
Subtract 344 from 400 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 8:
560 divided by 86 is 6 with a remainder of 44.
Write down 6 as next digit of the result. 
Result so far: 8341.46
Subtracting 516 from 560 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Advancing to step 9:
86 can be fit into 440 5 times, resulting in a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 8341.465
Subtracting 430 from 440 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 10:
100 divided by 86 is 1 with a remainder of 14.
Put 1 as the next digit of the answer. 
Result so far: 8341.4651
If we take 86 away from 100, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 11:
The number 86 fits into 140 1 times, leaving a remainder of 54.
Put 1 as the next digit of the answer. 
Result so far: 8341.46511
If we take 86 away from 140, we end up with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

The final result is 8341.46511 with a remainder of 5.4e-05.
